摘要：
An apparatus to upgrade software for a control device of a process control system, the apparatus comprising a first existing component (320, 310-312) to determine when a second existing component (310-312) of the software in a functioning control device (150-152) is at least one of failed, failing, or producing errors, each of the first and second existing components implementing a respective instantiation of the same software; and an upgrade module to instantiate a replacement component of the software in the functioning control device currently executing the second existing component that is at least one of failed, failing, or producing errors; and change the replacement component in the functioning control device to an active mode when a first state of the replacement component matches a second state of one of the first or second existing components.
